Title: Two-speed rear axle assembly
Inventor: WUEST GERALD A
IPC: F16H63/04
Filed: 1985-01-07
Abstract: A rear axle assembly for a vehicle includes an input shaft 22 connected by a driving shaft to the vehicle engine and an output shaft 24 connected to the vehicle differential ring gear 50. A pair of differently sized input gears 34,36 are splined onto the input shaft. Each of the input gears meshes with a respective output gear 54,52 rotatably supported on the output shaft. A slidable clutch collar 74 selectively clutches one of the output gears to the output shaft for driving the differential ring gear at a predetermined speed ratio. The clutch collar is actuated by a shifter assembly having a clutch fork 78 slidably maintained on a axially-movable shift rod 80 between a pair of opposed springs 86,88. Movement of the shift rod by the operator of the vehicle causes the springs to exert a predetermined bias force against the shift fork. The clutch collar is thereby moved from engagement with one output gear to the other when the friction force between the clutch collar and the one output gear becomes less than the force exerted by the springs on the clutch collar. <IMAGE>
Patent GB-2170420-A (GB)
Title: Filtration apparatus
Inventor: CHERN JIUNN-ING
IPC: B01D29/00
Filed: 1985-02-06
Abstract: Water is fed to a filter chamber 1 enclosing filter elements 7 from an overhead supply tank 3, and filtered water flows to outlet 38 through storage chamber 2 above the filter chamber. As elements 7 clog, the level in siphon 5, connected to chamber 1 on the upstream side, rises until it overflows the siphon at 5c, causing a valve in vessel 6 downstream of the siphon to open. Thereupon the contents of chamber 2 are backflushed through elements 7 and over siphon 5 to outlet 25. When chamber 2 is empty, line 8 breaks the siphon action, and the valve is automatically closed to start a new filtering cycle.   <IMAGE>

Patent GB-2161909-A (GB)
Title: Gun sighting arrangement
Inventor: ZANKER PHILIP MICHAEL
IPC: F41G1/54
Filed: 1985-06-20
Abstract: A gun sighting arrangement comprises a focussing means, eg a telescope 11, mounted on a gun barrel 1 and pre-aligned with the gun barrel and the normal gunnery sight 9 on a standard-distance target. Relative movement between the gun muzzle and the gunnery sight 9, due, for example, to shock displacement of the sight or temperature distortion of the barrel, causes an error in barrel/target alignment when the gunnery sight 9 is on target. This error has two components (a) between gunnery sight sightline and barrel mounting, due to shocks etc and (b) between barrel mounting and muzzle, due to wear, temperature distortion of the barrel etc. Both of these effects can be compensated by mounting the telescope 11 at the muzzle end of the barrel 1. Muzzle displacement due to either effect causes displacement of the target image in the telescope 11, which may be produced by flashing the target with the standard range finding laser. The displacement indicates the alignment error. Partial compensation can be provided by mounting the telescope 11 at the barrel mounting (14 Fig. 4) and otherwise taking account of barrel distortion. <IMAGE>

IPC: B60R25/01
Filed: 1988-04-09
Abstract: The device having quick release backs (12) to the front seats (10) comprises a bracket (16) fixed to the seat squab (11) which supports a plunger type lock (18). The device also comprises a loop of stranded wire (25) which is secured by a tamperproof fastening to the seat back.

In this way, the seat backs obscure most of the driving controls and also glove compartment, radio and cassette player of the vehicle, providing both a deterrent to the casual thief and a means of positively immobilising the car so that it cannot be stolen. <IMAGE>
Patent GB-2219857-A (GB)
Title: Ultrasonic temperature sensors
Inventor: KULCZYK KONRAD
IPC: G08B17/00
Filed: 1988-06-15
Abstract: An ultrasonic fire detector 10 comprises an elongate ultrasonic waveguide, eg in the form of a wire 12 which is arranged to be strung around the area to be monitored for fire. An ultrasonic pulse generator 18 launches longitudinal ultrasonic pulses into one end of the waveguide, for reflection from the far end. The waveguide is arranged such that local heating due to a fire 30 changes its acoustic impedance at the location of the local heating, the change in acoustic impedance being sufficient to produce partial reflection of the ultrasonic pulses. Detection of the partially reflected pulses thus indicates the presence of a fire, and their time of arrival gives the location of the fire along the waveguide. The acoustic impedance change can be produced by providing the waveguide with notches filled with low melting-point alloy, by applying a temperature-induced stress to the waveguide, or simply by the temperature gradient caused by the fire. <IMAGE>

Title: Audible alarm arrangement
Inventor: TRIGGS PHILIP
IPC: B06B1/02
Filed: 1989-07-15
Abstract: An audible alarm arrangement comprises a transducer, eg of rocking armature form, with actuating means employing first and second wire coil components (9, 10) connected to a driver circuit incorporating a four-arm H-bridge network of switching devices (15, 16, 17, 18). A d.c. voltage supply (Vs) is connected to input terminals of the bridge network. The first wire coil component (9) is connected in series with a first capacitor (11) between output terminals (13, 14) of the bridge network as is also the second wire coil component (10) in series with a second capacitor (12). The switching devices (15, 16, 17, 18) are switched repeatedly between first and second states by an astable or bistable multivibrator circuit (Figs 3A, 3B) such that the switching devices (15, 16) in two diagonally opposite arms of the network are in the first state when the devices (17, 18) in the other two opposite arms of the network are in the second state. Increased drive voyage is effectively achieved in the transducer coils and hence increased sound output power compared with the prior art. <IMAGE>

Title: Voters for fault-tolerant computer systems
Inventor: STANDEVEN JOHN
IPC: G06F11/18
Filed: 1989-10-10
Abstract: A hardware voter suitable for use in a multi-channel computer system where nominally identical asynchronous messages are carried on the channels has (preferably FIFO) buffers 10 as channels, each buffer having an associated data sampler 11. A voting circuit 13 receives data from buffers 10, one slice (i.e. from each channel as many bits as the channel width) at a time and provides an output slice determined on the basis of the majority of the received slices. A circuit 15 controls the supply of the data from the buffers to the voting circuit, and also inhibits operation of a buffer in the event that its slice disagrees with those of the other channels. The control circuit may also inhibit operation of a buffer if it has no data slice to transfer to the voting circuit a predetermined time after the appearance of a data slice on one of the other buffers, ready for transfer to the voting circuit. <IMAGE>
